in this article, we survey the asymptotic stability analysis of fractional differential systems with the prabhakar fractional derivatives. we present the stability regions for these types of fractional differential systems. a brief comparison with the stability aspects of fractional differential systems in the sense of riemann-liouville fractional derivatives is also given.
it is commonly accepted that fractional differential equations play an important role in the explanation of many physical phenomena. for this reason we need a reliable and efficient technique for the solution of fractional differential equations. this paper deals with the numerical solution of a class of fractional differential equation. the fractional derivatives are described...
Fractional derivatives and integrals are new concepts of derivatives and integrals of arbitrary order. Partial differential equations whose derivatives can be of fractional order are called fractional partial differential equations (FPDEs). Recently, these equations have received special attention due to their high practical applications. In this paper, we survey a rather general case of FPDE t...
In this paper we will prove certain Hadamard and Fejer-Hadamard inequalities for the functions whose nth derivatives are convex by using Caputo k-fractional derivatives. These results have some relationship with inequalities for Caputo fractional derivatives.

We present the stability regions for these types of fractional differential systems.

In this article, we introduce the fractional differential systems in the sense of the Weber fractional derivatives and study the asymptotic stability of these systems. We present the stability regions and then compare the stability regions of fractional differential systems with the Riemann-Liouville and Weber fractional derivatives.
در این پایان نامه به بررسی دستگاه مستقل از زمان لورنز که یک دستگاه سه بعدی و غیر خطی می-باشد، می پردازیم. با تغییر روابط بین پارامترهای دستگاه، رفتارهای مختلفی که نقاط تعادل دستگاه از خود نشان می دهند را بررسی می کنیم. سپس با انتخاب یک پارامتر مناسب انشعاب، نشان می دهیم که یک انشعاب هاف در این دستگاه اتفاق می افتد. به همین منظور ابتدا دستگاه های معادلات دیفرانسیل به عنوان یک دستگاه پویا را بررس...
A universal approach by Laplace transform to the variational iteration method for fractional derivatives with the nonsingular kernel is presented; in particular, the Caputo-Fabrizio fractional derivative and the Atangana-Baleanu fractional derivative with the non-singular kernel is considered. The analysis elaborated for both non-singular kernel derivatives is shown the necessity of considering...
It is commonly accepted that fractional differential equations play an important role in the explanation of many physical phenomena. For this reason we need a reliable and efficient technique for the solution of fractional differential equations. This paper deals with the numerical solution of a class of fractional differential equation. The fractional derivatives are described...
in this paper, under appropriate oscillating behaviours of the nonlinear term, we prove some multiplicity results for a class of nonlinear fractional equations. these problems have a variational structure and we find three solutions for them by exploiting an abstract result for smooth functionals defined on a reflexive banach space. to make the nonlinear methods work, some careful analysis of t...
